▼ This dissertation concerns modeling two aspects of dynamics of complex networks: (1) response dynamics and (2) growth and formation. A particularly challenging class of networks are ones in which both nodes and links are evolving over time – the most prominent example is a financial network. In the first part of the dissertation we present a model for the response dynamics in networks near a metastable point. We start with a Landau-Ginzburg approach and show that the most general lowest order Lagrangians for dynamical weighted networks can be used to derive conditions for stability under external shocks. Using a closely related model, which is easier to solve numerically, we propose a powerful and intuitive set of equations for response dynamics of financial networks. We find the stability conditions of the model and find two phases: “calm” phase , in which changes are sub-exponential and where the system moves to a new, close-by equilibrium; “frantic” phase, where changes are exponential, with negative blows resulting in crashes and positive ones leading to formation of "bubbles". We empirically verify these claims by analyzing data from Eurozone crisis of 2009-2012 and stock markets. We show that the model correctly identifies the time-line of the Eurozone crisis, and in the stock market data it correctly reproduces the auto-correlations and phases observed in the data. The second half of the dissertation addresses the following question: Do networks that form due to local interactions (local in real space, or in an abstract parameter space) have characteristics different from networks formed of random or non-local interactions? Using interacting fields obeying Fokker-Planck equations we show that many network characteristics such as degree distribution, degree-degree correlation and clustering can either be derived analytically or there are analytical bounds on their behaviour. In particular, we derive recursive equations for all powers of the ensemble average of the adjacency matrix. We analyze a few real world networks and show that some networks that seem to form from local interactions indeed have characteristics almost identical to simulations based on our model, in contrast with many other networks.

▼ This work demonstrates the practicality of using variable order (VO) derivative operators for modeling the dynamics of complex systems. First we review the various candidate VO integral and derivative operator definitions proposed in the literature. We select a definition that is appropriate for physical modeling based on the following criteria: the VO operator must be able to return all intermediate values between 0 and 1 that correspond to the argument of the order of differentiation in addition to the integer order derivatives, and the derivative of a true constant function should be 0. Then we apply the chosen operator to 3 different problems: a stationary analysis of viscoelastic oscillators, the formulation of a Lagrangian equation of motion for a sedimenting particle in a viscous fluid, and the development of a constitutive equation for viscoelastic materials. In the first problem we obtain an analytical solution for the order of the operator and connect the meaning of functional order to the dynamic properties of a viscoelastic oscillator. We replace the multi-term differential equation for the viscoelastic oscillator with a single-term VO equation. We determine that the order of differentiation for a single operator describing all dynamic elements in the stationary equation of motion (mass, damping and spring) is equal to the normalized phase shift. The normalization constant is found by taking the difference between the order of the inertial term (2) and the order of the spring term (0) and dividing this difference by the angular phase shift between acceleration and position in radians (π), so that the normalization constant is simply 2/π. For the second problem we focus on the transient equation of motion for a spherical particle sedimenting in a quiescent viscous liquid. In particular, we examine the various force terms in the equation of motion and propose a new form for the history drag acting on the particle at finite Reynolds numbers. This new form equates the history drag to the VO derivative of the velocity of the particle. Using numerical results from a finite element simulation of the particle we solve for order of the derivative q and evaluate how the order changes over time. Based on these results we propose a simple form for q and obtain a correlation for the history drag acting on the particle that is in good agreement with the numerical data for terminal Reynolds numbers ranging from 2.5 to 20. In the final problem we present a simple constitutive equation for linear viscoelastic materials strained at constant strain rates. We propose a relationship in which the stress is related to the q(t) derivative of strain, where q(t) in this case is a function of normalized time. This order function is postulated to be proportional to the rate of change of disorder within the material. From a statistical mechanics based theory, we find that q(t) is proportional to tInt. Using experimental data for an epoxy resin and carbon/epoxy composite undergoing compression, we determine the final form for the…

▼ Recognition of the complexity of many public health problems has led to the search for analytic methods capable of capturing more fully than traditional study designs and statistical tests the underlying dynamic processes at work. Similarly, those with an interest in public health interventions have begun to see the limitations of standard methods in understanding the consequences of programs and policies designed to influence population-level health. While there are a number of system science methods with potential to further public health research, there are three methods most often applied: agent-based modeling, social network analysis, and system dynamics modeling. The first discussion reviews both theoretical and practical applications of these three methods in the literature, as each has strengths and weaknesses and is better suited to studying some aspects of complex dynamic phenomena than others. Such a discussion provides practical guidance for those who wish to use these system methods in their own research. Following this, there is a discussion of different perspectives on how these methods relate to traditional behavioral research methods, and how these perspectives affect understanding of and explanation of public health problems. Beginning with a detailed analysis of the three systems methods used in public health and following with a discussion of how different perspectives affect understanding of public health problems sets the stage for the development of a systems model of a complex public health problem. The final section applies these lessons by developing and testing a system dynamics model of type 2 diabetes in the area known as Health Service Region 11. The model framed the problem of diabetes in this region using assumptions implicit within selecting a system dynamics model. The focus was on the effectiveness of physical activity interventions to guide decision-makers in future resource allocation and public health professionals to use appropriate methodologies for complex health problems that traditional linear approaches are unable to capture and thus unable to suggest informed routes for change. The model evaluated different “what if” scenarios of prevention and intervention strategies for reducing prevalence of (and ultimately incidence of) type 2 diabetes.

▼ Human health conditions, such as adverse drug reactions (ADR) caused by drug-drug interactions (DDI), are too complex to be tackled effectively by a single domain of expertise. Their associated wide range of data sources, from electronic health record (EHR), social media, to the published scientific literature, requires an interdisciplinary approach common to complexity science and its sub-fields of data and network science. We divide our work in three parts. Using city-wide public health care dispensation records from Blumenau—a mid-size city in southern Brazil—we report primarily on the large number of major DDI being prescribed, with women having a 60% increased risk of DDI when compared to men—the increased risk becomes 90% when only major DDI are considered; this DDI risk also increases with age, with patients age 70-79 having a 34% risk of DDI when they are dispensed two or more drugs concomitantly; and our ability to correctly classify patients with DDI using machine learning techniques. Then we study and predict DDI and ADR from social media data. We focus on different cohorts of interest, for which we build networks from Instagram and Twitter timelines. The network analysis uncovers population-level associations of drugs and symptoms, useful for public health surveillance, as well as affords a means to identify edges to predict putative known and unknown DDI and ADR. Lastly, we present a preliminary study of the timing of DDI observation across different data sources such as social media, clinical reports, and the scientific literature on DDI. We select a set of DDIs and show that social media measurements of DDI and ADR mentions may precede scientific literature when large longitudinal social media data is available. We exemplify with the case for the co-administration of opioids and benzodiazepines. Overall, the results we present in this thesis have important consequences for private and public health policy and regulation, further demonstrating that the methods of complexity science are very useful for studying DDI in particular and public health in general, to the benefit of society.

▼ Complex products have been of interest to academics and practitioners. This interest has recently been intensifying as the set of complex products are growing by advancements in science and technology. This thesis studies these products from the product development and supply chain perspectives. Utilizing these perspectives, complex products are complex systems. As complex systems, they have hierarchy orders in which some elements have more influence on others. Deploying the Product Development (PD) perspective, product and organizational architec- tures of complex products have been expected to be associated. However, the empirical observa- tions have partially supported this expectation. Therefore, misalignments can occur in complex product development. Despite their occurrence, the literature of complex products lacks models that examine the PD performance effects of misalignments. Using the Complex Adaptive Systems (CAS) view, the PD part of this research develops a NK(C) fitness landscape simulation model. In the developed model, PD teams search on a per- ceived landscape rather than the real landscape that makes them undergo some performance degra- dations. Such performance degradations occur as two types of errors: Type I errors of rejecting a superior design and Type II errors of accepting an inferior design. The Supply Chain (SC) part of this thesis studies complex products from SC perspective. In this part, the set of firms operating to develop a complex product have been considered as a complex Supply Network (SN). The inefficiency of these SNs has not received adequate attention from scholars and its inefficacy has not been studied. Taking a CAS view, a network game model of complex SNs is developed in this dissertation. In this model, firms as agents make decisions on their level on integration with and differentiation from their neighbour firms. Their decisions are mainly myopic optimizing their local performance rather than the SN performance. To study inefficiency of SNs, a decision space is defined and examined. The decision space in which firms’ integration decisions more than their myopic firm-level integration improves the SN performance is considered as a SN inefficiency measure. A set of experiments are conducted on the PD model. The experiments compare the PD performance of the two misalignment forms. They also examine the PD performance effects of misalignments at different hierarchical levels. The results of the Type I and Type II experiments demonstrate completely different patterns. According to these results, some possible PD strategies to manage the PD performance effects of misalignment are identified. By analysis of the SN model, the SN part of this thesis identifies some strategies that managers can apply to manage their SN inefficiency. The interactions pattern and hierarchy in the complex SN are…

▼ Parents of children with high-level support needs, including adult children, commonly interact with service providers across health, disability, education and other systems. In a policy environment that emphasises individual autonomy and the marketisation of service provision, however, parents’ relationships with such systems remain unclear. This qualitative study explored the ways that parents construct their relationships with providers, and their views about their own identities within and outside the formal service systems with which they interact. A theoretical framework of social constructionism, complexity theory, and critical postmodern feminism informed the study design and the interpretation of data. Twenty-seven parents, from metropolitan and non-metropolitan areas across five Australian states, participated in semi-structured in-depth interviews and created concept maps to describe their service system relationships. The data were analysed using a thematic network analysis (Attride-Stirling, 2001), from which three key themes emerged. A theme of “boundaries” captured the ways that parents defined their own identities, and those of providers. “Transition” highlighted times of change as particular occasions of challenge and opportunity in the negotiation of parent identities and relationships. The third theme, “enacting power through control and resistance” reflected parents’ understanding of the role of power in their relationships with providers. The findings suggest that a life-course approach contributes to a better understanding of the unique, complex and dynamic relationships between parents and service providers than current service models that reflect the developmental stages of childhood, adolescence and adulthood. The global theme of “individual (re)negotiation” sheds light on parents’ constructions of identity and their active participation towards more equitable relationships with providers. The findings of the study have implications for more inclusive, co-relational practices. The thesis discusses the findings’ significance for policy, practice, education and future research.

▼ Patterns in biology, chemistry, physics and mathematics can occur from self-organization and the interaction of constituents. In this thesis defense, I will explore patterns in two very different systems: (i) “chimera states” in a biologically-relevant model of excitable tissue, namely a modified version of the FitzHugh-Nagumo model, and (ii) collective motion of living many-agent systems such as swarms of brine shrimp. The FitzHugh-Nagumo model is a simple dynamical system that adequately describes many phenomena in excitable biological systems, such as firing neurons. The excitability is modeled via cubic terms added to the otherwise linear differential equations that describe the time evolution of two dependent variables that characterize the state of a cell. When many of these cells are then coupled in space, the model results in either a stable fixed point or a stable limit cycle which describes synchronized oscillating cells. However, chimera states in which stable fixed-point and limit-cycle regions coexist are not described within this model, even though they are observed in the heart and the brain. By adding a 5th order term in the membrane potential to this 3rd order system, we can recover chimeras, dependent on only initial conditions of the cells. Chimeras have previously been shown in systems with non-local coupling. Interestingly, however, they appear in this new system with purely local coupling. We study the dynamics of these chimeras in a few situations: in 1-dimensional cables and rings with two different simultaneous dynamics and in 2-dimensional grids representing tissues. Switching gears, I then discuss the patterns that occur in swarming, a self-organization phenomenon exhibited in many biological systems such as flocks of bird and insect, schools of fish, and collections of bacteria. This sort of behavior emerges spontaneously, arising without any sort of centralized control or leadership. Many crustaceans such as brine shrimp produce swarms, in which individuals cluster together rather than spread out uniformly in their environment. The size and distribution of these swarms are governed by local interactions between individuals. We will discuss the three-dimensional patterns that can be observed in brine shrimp swarms, specifically of the Great Salt Lake strain of Artemia franciscana, at high concentration. These patterns can be easily observed with simple tabletop experiments. We experimentally test the effects of certain environmental conditions on the dynamics of the individuals and on the development of these swarms. Advisors/Committee Members: Fenton, Flavio H.

▼ Conceptualizations of earth's surficial systems pose challenges to scientists, novice teachers, and students alike, because they are variable, non-linear, and dynamic. Developing scientific models of these systems allow users to visualize, manipulate, reason, and organize knowledge about the system under investigation. This dissertation is focused on two research strands using scientific modeling of surficial earth systems. The first strand is focused on a coastal ecosystem impacted by soil salinization and water availability. This study used topography, soil type, soil conductivity, and plant community to develop a conceptualized toposequence of this region to support our understanding of the dominant source of soil salinity. The second strand is twofold: novice understanding of scientific modeling and conceptual model development. The first study evaluates novice science teachers' approach to scientific modeling of a system which they have no prior knowledge about. Through observations, we assessed their science process skills, compared these results to novices and experts working with the same system, and found that novice teachers perform more like novices when faced with scientific investigations. This research will guide future teacher professional development programs to explicitly focus on science process skills and their role in scientific modeling. The second study characterizes the impact of an inquiry-based learning (IBL) module versus a traditionally structured laboratory exercise. The experimental groups were taught using IBL pedagogical techniques through manipulation of large-scale data sets, multiple representations, and a physical model. The control groups were taught traditionally. The groups were not significantly different prior to exposure to the lesson. Pre/post-expressed conceptual models indicate that the experimental group had greater increases in critical thinking. Written reports indicated they further gained in content knowledge, communication of findings, and experimental design. Overall results showed that teaching though IBL coupled with multiple representations had significant positive influence on student's conceptual model development. This synergistic dissertation between science and science education is a model for those wanting to pursue an academic career in geoscience education. This type of synergy between teaching and research allows for greater achievement in and outside the classroom ultimately improving overall education. Advisors/Committee Members: Herbert, Bruce E.

▼ Detailed Monte-Carlo simulation of a complex system is the benchmark method used in probabilistic analysis of engineering systems under multiple uncertain sources of failure modes; such simulations typically involve a large amount of CPU time. This makes the probabilistic failure analysis of complex systems, having a large number of components and highly nonlinear interrelationships, computationally intractable and challenging. The objective of this thesis is to synthesize existing methods to analyze multifactorial failure of complex systems which includes predicting the probability of the systems failure and finding its main causes under different situations/scenarios. Bayesian Networks (BNs) have potentials in probabilistically representing complex systems, which is beneficial to predicting the systems failure probability and diagnosing its causes using limited data, logic inference, expert knowledge or simulation of system operations. Compared to other graphical representation techniques such as Event Tree Analysis (ETA) and Fault Tree Analysis (FTA), BNs can deal with complex networks that have multiple initiating events and different types of variables in one graphical representation with the ability to predict the effects, or diagnose the causes leading to a certain effect. This thesis proposes a multifactor failure analysis of complex systems using a number of BN-based approaches. In order to overcome limitations of traditional BNs in dealing with computationally intensive systems simulation and the systems having cyclic interrelationships (or feedbacks) among components, Simulation Supported Bayesian Networks (SSBNs) and Markov Chain Simulation Supported Bayesian Networks (MCSSBNs) are respectively proposed. In the latter, Markov Chains and BNs are integrated to acquire analysis for systems with cyclic behavior when needed. Both SSBNs and MCSSBNs have the distinction of decomposing a complex system to many sub-systems, which makes the system easier to understand and faster to be simulated. The efficiency of these techniques is demonstrated first through their application to a pilot system of two dam reservoirs, where the results of SSBNs and MCSSBNs are compared with those of the entire system operations simulation. Subsequently, two real-world problems including failure analysis of hydropower dams and nuclear waste systems are studied. For such complex networks, a bag of tools that depend on logically inferred data and expert knowledge and judgement are proposed for efficiently predicting failure probabilities in cases where limited operational and historical data are available. Results demonstrate that using the proposed SSBN method for estimating the failure probability of a two dam reservoir system of different connections/topologies results in probability estimates in the range of 3%, which are close to those coming from detailed simulation for the same system. Increasing the number of states per BN variables in the states’ discretization stage makes the SSBN results converge to the simulation results.…

▼ In order to understand how the interactions of molecular components inside cells give rise to cellular function, creating models that incorporate the current biological knowledge while also making testable predictions that guide experimental work is of utmost importance. Creating such models is a challenging task in complex diseases such as cancer, in which numerous components are known to play an important role. To model the dynamics of the networks underlying complex diseases I use network-based models with discrete dynamics, which have been shown to reproduce the qualitative dynamics of a multitude of cellular systems while requiring only the combinatorial nature of the interactions and qualitative information on the desired/undesired states. I developed analytical and computational tools based on a type of function-dependent subnetwork that stabilizes in a steady state regardless of the state of the rest of the network, and which I termed stable motif. Based on the concept of stable motif, I proposed a method to identify a model's dynamical attractors, which have been found to be identifiable with the cell fates and cell behaviors of modeled organisms. I also proposed a stable-motif-based control method that identifies targets whose manipulation ensures the convergence of the model towards an attractor of interest. The identified control targets can be single or multiple nodes, are proven to always drive any initial condition to the desired attractor, and need to be applied only transiently to be effective. I illustrated the potential of these methods by collaborating with wet-lab cancer biologists to construct and analyze a model for a process involved in the spread of cancer cells (epithelial-mesenchymal transition), and also applied them to several published models for complex diseases, such as a type of white blood cell cancer (T-LGL leukemia). These methods allowed me to find attractors of larger models than what was previously possible, identify the subnetworks responsible for the disease and the healthy cell states, and show that stabilizing the activity of a few select components can drive the cell towards a desired fate or away from an undesired fate, the validity of which is supported by experimental work.

▼ The thesis applies complex dynamic system thinking to the context of place, people and policy. The thesis aims to contribute to closing an identified gap in policy literature and practice; specifically exploring the theoretical and practical advantages of a policy development model that is more reflective of contextual reality. This research explores and demonstrates the development of policy with a particular focus on place and people. The application of dynamic systems management to place, people, and policy is made viable through the development of a meta-framework that connects dimensions and their associated multiple perspectives. In particular, the thesis demonstrates how the use of a metaframework can assist the representation, understanding, explanation and utilisation of the complexity derived from societal connections, dynamics and contestability to create value through the design, implementation and evaluation of policy. The combination of information and the meta-framework structure supports a narrative that links cause with effect at and between both the practice and strategic dimensions across activities and outcomes that are relevant to people. It further allows, and arguably requires, interests to generate narratives within similar constructs as the basis for community conversations. The meta-framework is first elaborated and then applied to cases studies in different policy arenas. The case studies demonstrate the extension of what may simply be seen as a heuristic device for policy analysis into dynamic applications within place-based development. The cases combine literature with practice to reflect differing contexts: • socio-economic pathways to new sectoral and community futures; • industry fit to place, emerging values and thinking; and • combining latent endogenous capital with emerging macro trends/policy to create new opportunity. The analysis of the case studies supports the proposition that the introduction of a dynamic systems logic meta-framework into public policy making: • can provide a framework within which to apply and further develop concepts and tools that are useful in supporting the integration of multiple perspectives and complexity thinking; • can improve public policy performance and productivity, and contribute to improved resource allocation, and measurement of success; and • can support the proposition that understanding complexity provides the potential to identify innovative policy initiatives.

▼ This dissertation covers the two major parts of my Ph.D. research: i) developing a theoretical framework of complex networks and applying simulation and numerical methods to study the robustness of the network system, and ii) applying statistical physics concepts and methods to quantitatively analyze complex systems and applying the theoretical framework to study real-world systems. In part I, we focus on developing theories of interdependent networks as well as building computer simulation models, which includes three parts: 1) We report on the effects of topology on failure propagation for a model system consisting of two interdependent networks. We find that the internal node correlations in each of the networks significantly changes the critical density of failures, which can trigger the total disruption of the two-network system. Specifically, we find that the assortativity within a single network decreases the robustness of the entire system. 2) We study the percolation behavior of two interdependent scale-free (SF) networks under random failure of 1-p fraction of nodes. We find that as the coupling strength q between the two networks reduces from 1 (fully coupled) to 0 (no coupling), there exist two critical coupling strengths q1 and q2 , which separate the behaviors of the giant component as a function of p into three different regions, and for q2 < q < q1 , we observe a hybrid order phase transition phenomenon. 3) We study the robustness of n interdependent networks with partially support-dependent relationship both analytically and numerically. We study a starlike network of n Erdos-Renyi (ER), SF networks and a looplike network of n ER networks, and we find for starlike networks, their phase transition regions change with n, but for looplike networks the phase regions change with average degree k . In part II, we apply concepts and methods developed in statistical physics to study economic systems. We analyze stock market indices and foreign exchange daily returns for 60 countries over the period of 1999-2012. We build a multi-layer network model based on different correlation measures, and introduce a dynamic network model to simulate and analyze the initializing and spreading of financial crisis. Using different computational approaches and econometric tests, we find atypical behavior of the cross correlations and community formations in the financial networks that we study during the financial crisis of 2008. For example, the overall correlation of stock market increases during crisis while the correlation between stock market and foreign exchange market decreases. The dramatic increase in correlations between a specific nation and other nations may indicate that this nation could trigger a global financial crisis. Specifically, core countries that have higher correlations with other countries and larger Gross Domestic Product (GDP) values spread financial crisis quite effectively, yet some countries with small GDPs like Greece and Cyprus are also effective in propagating systemic risk and…

▼ Many geophysical phenomena present emergent behaviour, which manifested as large-scale statistical regularities such as power-law distributions for the coarse-grained observables of the corresponding systems. In this thesis we investigate the appearance of power-law distributions in geophysical phenomena. We develop a statistical technique for making accurate estimations of the parameters of power-law distributions. The method introduced, which gives an objective criteria to decide the power-law domain of the distribution, is applied to investigate the half-lives of radioactive elements, the seismic moment of earthquakes, the energy of tropical cyclones, the area burnt in forest fires and the waiting time between earthquakes. In addition, the method is applied for investigating the reproducibility of the observation of scale-free rain event avalanche distributions using data across diverse climates and for looking for signs of universality in the associated fitted exponents. Scaling techniques are also applied in order to see the collapse of the distributions. This study contributes to a recent array of statistical measures that give support to the hypothesis that atmospheric convection and precipitation may be a real-world example of Self-Organised Criticality (SOC, a mechanism able to reproduce the observed power laws). Another expectation of the SOC paradigm is universality, but the fitting method is not enough for checking this hypothesis. Therefore, a method based on a permutation test is developed in order to determine if the estimated exponents are statistically compatible. Our alternative permutational tests give clear results: despite the fact that the differences between the exponents are rather small, the universality hypothesis is rejected. However, the fact that the universality hypothesis is rejected in the tests does not mean that one has to rule out the existence of a universal mechanism for atmospheric convection, as uncontrolled systematic errors can be present in the collection of data. Finally, we study the consequences of the previous results for the prediction of atmospheric phenomena by analysing the effect of applying thresholds on SOC models and rainfall time series. The predictability of extreme events and extreme intensities is studied by means of a decision variable sensitive to the tendency to cluster or repulse between them and the quality of the predictions is evaluated by the receiver operating characteristics method. On the events scale (large scale), times between events for rainfall data and models renormalise to a trivial point process, and then the predictability decreases when the threshold increases. In the intensity picture (short scale), the prediction is not affected by the threshold, as the process remains mostly unchanged (also their critical corresponding exponents) until very high thresholds are reached.

▼ Complex systems often result in intractable mathematical models when classical methodological reduction methods are used in modeling. As a result, reduction methods more holistic in nature are normally used to avoid modeling on a component scale. In this dissertation, several new reduction methods are proposed with the intent of extending the application of classical methodological reduction methods to complex systems. As a motivating example, a large scale self-similar potential-driven tree network is used as a model complex system. In the linear case, the self-similarity present in the physical system is translated to a self-similarity in the mathematical model. This is in turn used to analytically reduce an otherwise intractable DAE system to a much simpler ODE. It is also shown that for very large systems, it can sometimes be advantageous to approximate the system as infinite in scale. In the non-linear case, two numerical algorithms are presented to simplify dynamic analysis of piping networks. These methods are based on Chorin’s multi-step projection method for solving the Navier-Stokes equations. In addition to the self-similar tree network, other self-similar network structures are considered. In particular, grid-like networks are considered, and potential reduction methods are proposed. Finally, in the course of studying the self-similar potential-driven tree network the appearance of fractional-order derivatives is noted several times. Based on this observation, fractional-order system identification is proposed as an extension of typical black-box reduction methods and experimental data acquired from a shell-and-tube heat exchanger is used to demonstrate its usefulness. While the analysis presented is in terms of potential-driven transport networks, it should be noted that the specific examples used were chosen for their simplicity. But the methods used should be more generally applied to the reduction of self-similar complex systems, and even more generally, to large equation sets and DAE systems. Futhermore, the repeated appearance of fractional-order operators, and as a special case, fractional-order derivatives and integrals, suggest a very rich relationship between self-similar complex systems and fractional calculus.

▼ This dissertation examines human settlement-size variation through the lens of hunter-gatherer archaeology. Research article 1 presents an analysis of prehistoric hunter-gatherer settlement patterns from a wide range of environmental contexts and in the absence of socioeconomic complexity. Hunter-gather settlement size variation is found to exhibit heavy-tailed statistical structure that is consistent with the statistical structure of modern settlement-size variation, supporting claims that socioeconomic complexity is not requisite for the formation of so-called settlement-size hierarchies in human societies. Following insights from hunter-gatherer anthropology, complex systems research, and ecology, research article 2 proposes that the structure of hunter-gatherer site-size variation is an emergent property of obligate tool use among mobile hunter-gatherers. As materials are moved, modified, and deposited on the landscape, they effectively subsidize the costs of future land use at those locations, which results in additional material deposition, attracting future use, and so on. Using an agent-based model, it is demonstrated that this recursive niche-construction behavior is sufficient to generate the heavy-tailed property of hunter-gatherer site-size variation. The working model is then used to predict other dimensions of hunter-gatherer settlement structure related to artifact clustering and site occupation histories. Research articles 2 and 3 present test results based on Late Archaic Period (7,000-5,000 B.P.) settlement patterns in the Lake Titicaca Basin, Peru. Good agreement is found between the predictions and empirical observations suggesting that ecological niche construction may have played a significant role in structuring hunter-gatherer mobility and land use, which in turn may have created a context for emergent settlement hierarchies.

▼ The creation and use of models is critical not only to the scientific process, but also to life in general. Selected features of a system are abstracted into a model that can then be used to gain knowledge of the workings of the observed system and even anticipate its future behaviour. A key feature of the modelling process is the identification of commonality. This allows previous experience of one model to be used in a new or unfamiliar situation. This recognition of commonality between models allows standards to be formed, especially in areas such as measurement. How everyday physical objects are measured is built on an ingrained acceptance of their underlying commonality. Complex systems, often with their layers of interwoven interactions, are harder to model and, therefore, to measure and predict. Indeed, the inability to compute and model a complex system, except at a localised and temporal level, can be seen as one of its defining attributes. The establishing of commonality between complex systems provides the opportunity to find common metrics. This work looks at two dimensional cellular automata, which are widely used as a simple modelling tool for a variety of systems. This has led to a very diverse range of systems using a common modelling environment based on a lattice of cells. This provides a possible common link between systems using cellular automata that could be exploited to find a common metric that provided information on a diverse range of systems. An enhancement of a categorisation of cellular automata model types used for biological studies is proposed and expanded to include other disciplines. The thesis outlines a new metric, the C-Value, created by the author. This metric, based on the connectedness of the active elements on the cellular automata grid, is then tested with three models built to represent three of the four categories of cellular automata model types. The results show that the new C-Value provides a good indicator of the gathering of active cells on a grid into a single, compact cluster and of indicating, when correlated with the mean density of active cells on the lattice, that their distribution is random. This provides a range to define the disordered and ordered state of a grid. The use of the C-Value in a localised context shows potential for identifying patterns of clusters on the grid.

▼ Monodrama is a work for a sole protagonist, utilising both sung and spoken vocalism over a cathartic narrative. Developed as a subgenre of opera relatively recently, monodrama emerged in the era of Freudian psychology. Monodrama aims to convince the audience of the authority and infallibility of the protagonist’s point of view. An operatic monodrama rehearsal is a unique sociological dynamic, one that functions as a complex adaptive process with director, conductor and performer as principal agents. The effective functioning of this dynamic causes beneficial coherence, measurable by successful performance outcomes (Snowden, 2012). An interesting phenomenon is observed in monodrama rehearsals, divergent from traditionally hierarchical rehearsal dynamics found in opera. The singer has increased agency in rehearsal, effectively transforming the dynamic from a negotiation between stage director and conductor, as occurs in opera, into a collaboration of equal yet distinct roles. Director, conductor and performer form a triumvirate of mutual respect, exhibiting porous boundaries of roles and responsibilities (or linkages). Monodrama rehearsals comprise a series of “safe to fail” experiments, repeating acceptable patterns with mutual agreement of three principal participants (or nodes), and creating unique norms leading to successful performance. The relative agency of each participant in a rehearsal, changing notions of authorship, and the success of this complex collaboration are discussed in detail, showing the possibilities for adaptive rehearsal structures in a traditionally conservative art-form. Primary research is conducted through participation as director and singer in three monodrama production rehearsal periods: “Pierrot Lunaire” by Arnold Schoenberg, “The Seven Deadly Sins” by Kurt Weill, and “The Pomegranate Cycle” by Eve Klein. Industry professionals’ perceptions of the dynamics in monodrama and opera rehearsals are also studied through semi-structured interviews and surveys with thirteen subjects (N=13), four directors (D=4), four conductors (C=4) and five singers (P=5), considering self-reported “successful” performance in opera and monodrama. Both the performance practice research and qualitative research herein supports the hypothesis that a monodrama rehearsal is a collaborative triumvirate functioning as a complex adaptive system, contrasting with the power structures and dynamics commonly observed in opera rehearsals.
